Vootu LED Tube Application Notes
Differentiating between the different LED tube offerings from Vootu and when to use each
type of tube for the proper LED lighting solution
In this application note we will discuss specifically which T8 4’ LED tube in the Vootu product
line is the right solution for the applications encountered in the field.
First off let’s look at each tube type and learn what the differences are as far as installation and
power connection. UL/DLC has safety standards as far as the manner of which tubes are
powered. Vootu has developed LED tubes to meet these requirements and at the same time
minimize install costs. We will discuss three different power connection arraignments and tube
types which include, dual ended power (with micro switch), single ended power, and ballast
compatible/dual ended power.
T8 LED Tube 4’ 18W Dual ended power with Micro Switch End Cap:
Vootu Part # VT-T812-18WFO2
This is the main tube to use for most all applications. It meets UL/DLC so your customer can get
all rebates offered. It also is the quickest to install since simply bypassing the ballast and wiring
one side of the fixture to the hot wire and the other side to neutral is all that is required (see

attached wiring diagram and data sheet). There is no need to change the shunted tombstones
to non-shunted as is the case with most single ended power LED tubes which do require
replacing one tombstone for each tube. This configuration of LED tube is the most energy
efficient, maximum lumen output, and easiest and quickest install. This style tube should be
used in those applications that have long burn times (in excess of 10-12 hours per day) . This
tube will replace a 32 W florescent tube.
T8 Tube 4’ 18/22 W Hybrid Ballast Compatible
Vootu Part # VT-T8-18WFO3
VT-T8-22WFO3
This hybrid LED tube is very unique in that it can work with and without the ballast connected.
It is well suited for those instances when you want to do a quick “proof of concept” without
having to bypass the ballast. It does not require new tombstones when the ballast is bypassed
(when the ballast fails) like single ended power LED tubes since it a dual ended powered tube. It
also meets UL Standards.
This tube is well suited for shorter burn times where the install cost of bypassing the ballast
may be prohibitive to a low ROI. This tube should only be used for burn times of 10-12 hours or
less. For those higher burn times, and whenever it is feasible, the dual ended micro switch end
cap tube should be used. (Please see attached data sheet and wiring diagram) . The lumen
output of this tube is also less when the ballast is in the circuit. This is due to the design of the
energy saving electronic ballasts. When installed with the ballast bypassed the lumen output
will be greater. Note that these tubes will not work with any magnetic ballast and will only work
with true electronic ballasts. It is advised that you install a few tubes in different fixtures to test
the compatibility of these tubes with your customer’s fixtures.

T8 LED Tube 4’ 18W Single ended power :
Vootu Part # VT-T812-18WFO1
VT-T812-22WFO1
These tubes have all the same features and functions, electrical components etc., as the T8 LED
Tube 4’ 18W Dual ended power with Micro Switch End Cap tubes, except the micro switch end
cap. It is a single ended power input (Please see attached data sheet and wiring diagram). It is
the lowest cost LED tube Vootu offers. That said it is most likely the most expensive tube to
retrofit/install. The reason being, in most cases the tombstones will be shunted and you will
need to replace them with non-shunted tombstones. This additional cost for the tombstones
and the additional labor to install them will most likely cost more overall than the Dual ended
power with Micro Switch End Cap tubes.

Warning for installation for ballast compatible tube:
1.
A test is required before making mass installation.
2.
Make sure the socket and lampholder of the fixture are not loose or damaged
3.
Make sure that you turn off power before making installation.
4.
Make sure that the length of the tube is suitable for the fixture
5.
This tube only works with specific electronic ballast, not all ballasts. Do not
connect this ballast compatible tube with magnetic ballast.
6.
This ballast compatible tube may not work with all ballasts because the ballast
may be special or old.

WARNING!
Rewiring of fluorescent fixtures for use with LED tubes should only be performed by individuals who have been properly trained
to perform basic electrical maintenance and repair. Please review these instructions thoroughly before proceeding!
Step 1: Before opening and disassembling the fixture, make sure power has been turned off at the main circuit breaker and
remove the bulbs from the fixture.
Step 2: From the examples below, identify the wiring configuration of your fixture which is a function of the ballast type. If
you have configuration “A” or “B,” skip to Step 5. If you have configuration “C” (single wire coming from the G13 socket
at the end of each tube) go to Step 3.

Step 3: For Instant Start Ballast (Type C) Only!!!
Low Profile
For each tube in the fixture, remove the
shunted (single-wire) G13 socket from
only the end of the bulb closest to where
the line and neutral wires enter the fixture
(for example, in the diagram above, the
ends marked by the red arrows).
Step 4:
For Instant Start Ballast (Type C) Only!!!
Depending on your fixture type, insert either
the Low Profile or Standard Profile, non-shunted
(two-wire) G13 sockets in the fixture openings
and make sure they snap securely into place.

Step 5: The energized or “live” end of your new LED tubes have Line (L) and Neutral (N) terminal pins as shown below. The pins
on the unenergized or “dead” end of the tube are only used to hold that end of the tube in the socket. Before
reconfiguring your wiring in Step 6, make sure the wires going to the G13 socket that will hold the “live” end of the tube
(ideally, the socket closest to where power enters the fixture) are arranged so that line voltage connects to the side of
the socket that will hold the “L” pin and that the neutral wire connects to the side of the socket that will hold the “N” pin.

Step 6: Remove or disconnect all of the wiring/starter/ballast indicated in red in the diagrams below. When removing or
cutting the wires from the G13 sockets at the “dead” end of the fixture, make sure that they are tight in the fixture and
will hold your new LED bulbs securely. Replace broken G13 sockets. If you elect to leave the starter, ballast, or cut
wiring in the fixture, or if it cannot easily be removed, make sure that all unused lead wires are wire nutted, rolled up,
and secured out of the way.
